KEROSENE-OIL BURNER.

Application filed June 8,

To all whom it may concern:

Be it known that I, EDWARD CURRIER, a citizen of the United States,residing at Fall River, in the county of Bristol and State ofMassachusetts, have invented a new and useful Kerosene-Oil Burner, ofwhich the fol lowing is a specification.

This invention aims to provide a device for converting kerosene oil orother liquids into gas, the gas being ignited and burning to produce thenecessary heat, novel means being provided for controlling andregulating'the heat, and novel means being provided for screening thefuel during its passage to the combustion orifice.

It is within the province of the disclosure to improve generally and toenhance thev utility of devices of that type to which the inventionappertains.

With the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, Within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the accompanying drawings:

Figure 1 shows in side elevation, a device constructed in accordancewith the invention; Figure 2 is a bottom plan; Figure 3 is a section onthe line 33 of Figure 2; Figure 4 is a section on the line 44 of Figure2; Figure 5 is a section on the line 5-5 of Figure 3; Figure 6 is atransverse section showing a portion of the combined spreader and screendelineated in Figure 5.

In carrying out the invention, there is .supplied a bowl or body 1. Athree-armed support 2 is secured to the upper edge of the bowl 1. Anadjusting device 3 preferably a screw, is mounted in the support 2. A

conical battle 4 is disposed in the bowl 1 at g the upper end thereofand has an upstanding marginal flange 5 spaced from the inner wall ofthe bowl. Nuts 6 secure the apex of the baiiie to the lower end of thescrew 3. By rotating the screw 3 in the support 2, the battle 4 may beraised and lowered for adjustment, the baflie being held in any positionto which it may have been adjusted, through the instrumentality of a nut7 threaded on the upper end of the screw and 1923. Serial No. 644,199.

adapted to engage the support 2. The bowl 1 has an opening 8 in itsbottom.

A retort, in the formof a coil 9 is located in the bowl 1. The inlet end10 of the coil extends downwardly and laterally, out of the opening 8 inthe bottom of the bowl as does the outlet end 11 of the coil. Clips 12,engaging the members 10 and 11, hold them on the bowl 1.

A union 14 is connected to the outlet end 11 of the coil 9'. To onemember or" the union 14, a nipple 15 is threaded. The nipple 15 isthreaded into one end of a T-coupling 16. Into the outer end of theT-coupling 16, a nipple 17 is threaded. A tubular screen 18 is mountedremovably in the nipples 15 and 17 and is spaced thereby from the boreof the coupling 16 as shown in Figure 4. Intermediate its ends, thescreen 18 has perforations 19 located opposite to the transverse branchof the coupling 16. At its outer end, the screen 18 is supplied with aflange 2O abutting against the outer end of the nipple 17. A cap 21 isthreaded on the outer end of the nipple 17 and, engaging the flan e 20of the screen 18, holds the screen in p ace removably.

A pipe 22 is located between the members 10 and 11 in parallel relationthereto. The pipe 22 is threaded into one end of a T-coupling 23disposed opposite to the T-coupling 16. The transverse branches of thecouplings 23 and 16 are united by a connection 24. A nipple 25 isthreaded into the outer end of the T-coupling 23. A cap 26 is threadedon the outer end of the nipple 25. The

inner end of the pipe 22 is threaded into a coupling 27, at one end ofthe coupling. Into the other end of the coupling 27 a nipple 28 isthreaded. A valve seat 29 is located in the coupling 27 and is heldthereby by the nipple 28. The seat 29 has a central opening 30. Theopening 30 is controlled by a needle valve 31 threaded into the nipple25.

Passing to the burner portion of the device, it is to be observed thatthe inner end of the nipple 28 is threaded into a T-coupling 32. Intothe outer end of the T-coupling 32 a nipple 33 is threaded. A tubularscreen 34 is located removably in the nipples 28 and 33. The screen 34has perforations 35 located opposite to the transverse branch of theT-coupling 32. The screen 34 is spaced by the nipples 33 and 28 from thebore of the T-coupling 32, as shown in Figure 3, The transverse branchofthe T-coupling 32 extends upwardly through the opening 8 in the bore 1.the screen 34 has a flange 36. The flange 36 abuts against the outer endof the nipple 33. A cap 37 is threaded on the outer end of the nipple33. The cap 37 engages the flange 36 of the screen 34 and holdsthescreenremovably in place. A vertical casing 38 is threaded into the transversebranch of the Tcoupling 32and. extends upwardly into the bowl ,1 at theaxis thereof. A cap 39 is threaded on the upper end of the casing 38.The cap 39 has a central burner orifice 41.

Within the casing 38 is located acombinedspreader and screen. Thecombined spreader and screen comprises a tubular stem 42 carrying anupper disk 43 and any desired number of lower disks 44. The disks 43 and44 have perforations 45. The upper disk 43 rests on the upper end of thecasing 38, the lower disks 44 being received in the casing. A rod 46 ismounted for limited reciprocation in the tubular stem 42. At its upperend, the rod 46 has a head 47. A securing element 48 is mounted in thelower end of the rod 46 and is spaced from the lower end of the tubularstem 42.

The fuel proceeding through the inlet end 10 of the coil 9, traversesthe coil and in the coil the fuel is thusformed wholly or in part intogas, by the flame proceeding from the burner orifice 41. The fuelleaves'the coil 9 by the outlet end 10, and as the fuel traverses thescreen 18, foreign matter in the fuel is removed. The fuel passes intothe pipe 22 throughthe connection 24 and the T-coupling 23. The flow ofthe fuel through the opening 30 in the valve seat 29 is regulated by theneedle valve 31. The tubular screen 34 exercises its obvious function asthe gas or fuel passes into the casing'38. Here the gas is screenedagain and is fed and distributed, by passing through the perforations 45of the disks 44 and 43. The gas emerging through the burner orifice 41in the cap 39 is ignited and produces a flame within the bowl- 1, theretort or coil being heated. The flow of the products of combustionupwardly and out of the bowl 1 may be regulated by raising and loweringthe baflie 4 as hereinbefore explained. screen 34 may be extracted forcleaning. Similarly, by removing the cap 21, the screen 18 may bewithdrawin -lVl1en the 7 cap .26 is detached, the needle valve 31 may beadjusted by means of a screw driver applied to the outer end of theneedle valve. Then the cap 39 is removed, therod 46 may be pulledupwardlyby the head 47 until the securing element 48 abuts against thelower end of. the stem 42, therod thus serving as a handle whereby the.spreader At its outer end,-
